Don’t use fancy language if it distracts the reader from understanding your writing. Get to the point and keep it simple.
This rule was taken from George Orwell’s Rules for Writing as published in the book Politics and the English Language.
Here’s the complete list:
(i) Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
(ii) Never use a long word where a short one will do.
(iii) If it is possible to cut a word out, always cut it out.
(iv) Never use the passive where you can use the active.
(v) Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
(vi) Break any of these rules sooner than say anything outright barbarous.
